Overview
The Texas Instruments 5962-9686901QCA is a military-grade SN54AHCT125 buffer and line driver featuring four non-inverting channels with three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V, ensuring TTL-compatible CMOS inputs. The device utilizes a CDIP-14 package and supports through-hole mounting. It functions reliably across an extended temperature range from -55°C to +125°C. Key electrical characteristics include an output drive capability of ±8 mA at 5 V and low static current consumption.
Feature Summary
- Military-grade reliability for harsh environments
- TTL-compatible CMOS inputs for direct interfacing
- Three-state outputs for bus-oriented systems
Applications
- Military communication systems
- Avionics data buses
- High-reliability industrial control interfaces
Procurement Notes
Verify the specific suffix QCA against the required datasheet revision and quality certification level. Confirm that the CDIP-14 package dimensions match the target PCB footprint. Ensure the 4.5 V to 5.5 V operating range aligns with the system power supply. Validate that the military temperature rating meets environmental specifications.
Selection Notes
Select this component when TTL-level input compatibility is required alongside high-speed CMOS performance in a military environment. The AHCT series ensures noise immunity while maintaining standard logic levels. The three-state feature allows multiple drivers to share a common bus without contention. Verify that the through-hole CDIP package is suitable for the assembly process.
Part Context
This part belongs to the SN54AHC/AHCT family of high-speed CMOS logic devices designed for military applications. The SN54AHCT125 variant specifically bridges TTL and CMOS logic families. The 5962 prefix indicates it is a military-grade version manufactured under strict quality controls. It serves as a buffer for signal integrity in critical digital systems.
Replacement Considerations
Cross-reference with other SN54AHCT125 variants having the same military suffix and package. Verify pinout compatibility before substitution. Ensure equivalent propagation delay and output drive strength are maintained.
